Extensively signed 1999 Athens #0049 Geoffrey Beetem jumbo Earth Orb

Hello I have a large Geoffrey Beetem Earth/World orb dated 1999 that I am looking to sell outright. It is approximately 5+ inches tall with extensive dichroic continental formations and detailed cloud effects. Geoffrey Beetem personally told me he valued this particular piece at $6,000. I have detailed photographs of the actual piece, including the 1999 signature/place of manufacturing, number 0049(extremely rare) and artists signature. Thank you
